.To @ZZ whom, it may concern:

Be 1t known that I, RAYMOND BALANS, of

ue de Dunkerque, Paris, in the Em- N o. 24 R pire of France,

drawing, and to the letters marked thereon.

My invention consists, c it-ion to ,jib-rings of a transversal rollerdividing the circle into two parts; and, secondly-,in

the addition to the said rings of a holdfastmethods at present employed.

The accompanying drawing represents a ring comprising these improvements.

a a are two shoulder-p1eces, formed one on each side ofthe inner circumference ofan ordinaryjibring, and serving as bearings to the axle shown b v the dotted liues,on which is mounted a roller with hollow or concave surface b b. c is the holdt'ast-hook by which the ring is attached to the corresponding eyelet ofthe jib. d is a cheelrpiece formed at each side of the ring, near the stalk of the hook, to

prevent displacement.

The hook closed, as in the drawing, is opened at will by simple linger-pressure on the outer face of the spring, or (if of considerable size) by aid of a small chain or other pull-piece set near the head ofthe latter. y I

he accompanying first, in the appli- The spring may be made of either brass oi steel, a desired; but in the larger sizes tht former will generally be found most eliicient, from its non-liability to oxidation.

1t may' here be remarked that the above mode eral purposes.

Among the advantages resulting' from the predescribed improvements may be noted, Iirst, substitution of Y friction at present exercised ou the rings and cai-responding cordage in setting the sail, and consequent decrease iu wear and tear; secondly, separation ofthe ropes in thc same ring by the presence ot' the transversal roller, and consequent suppression of knotting or entanglement; thirdly, facility in settingor 1, which can be effected by one-eighth ot' the force at present required; fourthly, facility and celerity in the bending' of the sail, which operation can, by aid ofthe holdi'ast-hook, be readily performed even by landsmen.

Having now described the nature otmy said invention and the manner of carrying it into eifect, I declare that what I claim, and desire to secure by Letters Patent, is

The application tojihsail rings of a transversal roller, dividing the circle into two parts,
